get_session_tracks

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It states it 'Get[s] all tracks' and returns a 'List of tracks in the session with performance context,' which hints at read-only behavior and output format. However, it lacks details on permissions, rate limits, pagination, error handling, or what 'performance context' entails (e.g., timestamps, ratings). For a tool with no annotation coverage, this is insufficient.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the core purpose in the first sentence, followed by structured 'Args' and 'Returns' sections. It's efficient with no redundant information. However, the 'Args' and 'Returns' formatting, while clear, could be slightly more integrated into a single narrative flow, preventing a perfect 5.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has an output schema (which likely defines the return structure), the description doesn't need to detail return values extensively. However, with no annotations and only basic parameter documentation, it lacks completeness for behavioral aspects like error cases or usage constraints. It's adequate but has clear gaps, making it a minimum viable description.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds meaningful context for the single parameter: 'session_id: The session's unique identifier.' Since schema description coverage is 0% (the schema only has a title 'Session Id'), this compensates well by explaining the parameter's purpose. With 0 parameters, the baseline would be 4, but here it effectively documents the one parameter, earning a 4.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb ('Get') and resource ('all tracks from a specific DJ history session'), making the purpose unambiguous. It distinguishes from siblings like 'get_history_sessions' (which lists sessions) and 'get_track_details' (which gets details for individual tracks). However, it doesn't explicitly differentiate from 'get_playlist_tracks' (which also gets tracks from a collection), so it's not a perfect 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage context by specifying 'from a specific DJ history session,' suggesting this is for retrieving tracks associated with a historical session rather than a playlist or other collection. However, it doesn't explicitly state when to use this versus alternatives like 'get_playlist_tracks' or 'get_recent_sessions,' nor does it mention prerequisites or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
